Abstract

The invention discloses a millimeter wave radar rotating device and a target tracking method thereof. The millimeter wave radar rotating device comprises a base body, a rotating control module, a pinrod and a rotating shell. The base body is fixedly mounted on a vehicle body; the rotation control module is fixedly arranged on the upper surface of the base body and comprises a controller, a servomotor, an output gear, a reduction gear and a pin rod gear. A hole for mounting the pin rod in the base body is coaxial with the bearing mounting hole in the base body, and is matched with the bearingto be mounted in the bearing mounting hole in the base body; the pin rod and the base body can rotate relatively; the upper surface of the rotating shell is fixedly connected with the lower end faceof the pin rod, and the lower surface is connected with the base body through a bearing. According to the invention, a rotating device with a simple structure is utilized to realize target tracking under the condition of using a single millimeter wave radar sensor.

Description

technical field [0001] The invention belongs to the technical field of radar detection, and specifically refers to a millimeter-wave radar rotating device and a target tracking method thereof. Background technique [0002] Millimeter wave radar has high precision, strong anti-interference ability, and small size, and is widely used in technical fields such as robot, drone, and unmanned vehicle target detection and target tracking. The millimeter-wave radar can detect the distance, speed, and azimuth of the target. The principle of measuring the azimuth is that the millimeter-wave radar has multiple receiving antennas in parallel, and the phase difference of the radar waves reflected by the same target received by different antennas can be calculated. Get the azimuth of the target. [0003] With the improvement of the level of science and technology, target tracking has become a hot issue under special working conditions such as special small-scale reconnaissance robots and ...
